Abstract

This document specifies a mechanism that enhances Proxy Mobile IPv6
protocol signaling to support the creation of a transient binding
cache entry that is used to optimize the performance of dual radio
handover, as well as single radio handover. This mechanism is
applicable to the mobile node's inter-MAG (Mobility Access Gateway)
handover while using a single interface or different interfaces. The
handover problem space using the Proxy Mobile IPv6 base protocol is
analyzed and the use of transient binding cache entries at the local
mobility anchor is described. The specified extension to the Proxy
Mobile IPv6 protocol ensures optimized forwarding of downlink as well
as uplink packets between mobile nodes and the network infrastructure
and avoids superfluous packet forwarding delay or even packet loss.
This document defines an Experimental Protocol for the Internet
community.
